A Variational Approach to Mutual Information-Based Coordination for Multi-Agent Reinforcement Learning

no code implementations1 Mar 2023 Woojun Kim, Whiyoung Jung, Myungsik Cho, Youngchul Sung

In this paper, we propose a new mutual information framework for multi-agent reinforcement learning to enable multiple agents to learn coordinated behaviors by regularizing the accumulated return with the simultaneous mutual information between multi-agent actions.

Quantile Constrained Reinforcement Learning: A Reinforcement Learning Framework Constraining Outage Probability

1 code implementation28 Nov 2022 Whiyoung Jung, Myungsik Cho, Jongeui Park, Youngchul Sung

This paper proposes a framework, named Quantile Constrained RL (QCRL), to constrain the quantile of the distribution of the cumulative sum cost that is a necessary and sufficient condition to satisfy the outage constraint.

Robust Imitation Learning against Variations in Environment Dynamics

1 code implementation19 Jun 2022 Jongseong Chae, Seungyul Han, Whiyoung Jung, Myungsik Cho, Sungho Choi, Youngchul Sung

In this paper, we propose a robust imitation learning (IL) framework that improves the robustness of IL when environment dynamics are perturbed.

A Maximum Mutual Information Framework for Multi-Agent Reinforcement Learning

no code implementations4 Jun 2020 Woojun Kim, Whiyoung Jung, Myungsik Cho, Youngchul Sung

In this paper, we propose a maximum mutual information (MMI) framework for multi-agent reinforcement learning (MARL) to enable multiple agents to learn coordinated behaviors by regularizing the accumulated return with the mutual information between actions.

Message-Dropout: An Efficient Training Method for Multi-Agent Deep Reinforcement Learning

no code implementations18 Feb 2019 Woojun Kim, Myungsik Cho, Youngchul Sung

In this paper, we propose a new learning technique named message-dropout to improve the performance for multi-agent deep reinforcement learning under two application scenarios: 1) classical multi-agent reinforcement learning with direct message communication among agents and 2) centralized training with decentralized execution.
